SPECIFICATION forming part of Letters Patent No. 404,711, dated June 4, 1889.

Application filed March 19, 1 889.

To all whom it may concern:

Be it known that I, JAMES W. JOHNSON, of La Due, in the county of Henry and State of Missouri, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference be ing had to the accompanying drawings,which form part of this specification.

My invention relates to an improvement in cultivators; and it consists in the combination of anumber of separate and distinct cultivators,with arched connecting-bars for uniting them together, pivoted blocks in which the ends of the arched rods are connected, and sockets secured to the plow-beams, in which the pivoted blocks are placed, as will be more fully described hereinafter.

The object of my invention is to connect four separate cultivators together by means of arched connecting rods or bars, so that all of the cultivators can be operated and controlled as if one, and thus two rows be cultivated at the same time at a great saving of labor and expense.

Figure 1 represents a side elevation of a cultivator which embodies my invention. Fig. 2 is a rear view of the same. Fig. .3 is a detached view.

A represents an arched axle, which is mounted upon the wheels B and to the top of which the two tongues G are secured. Secured to the under side of the tongues, in the rear of the draft-equalizer D, is the front cross-bar F, from the under side of which depend the hangers G, and between the lower ends of these hangers G the front ends of the cultivator-beams are fastened. The lower ends of the hangers are connected together by across-bar I, and upon this cross-bar is placed a loose sleeve J. The front end of each beam is turned at right angles to the beam, and this horizontal portion is pivoted between the rear ends of the clamp L, which is applied to the sleeve J. The sleeve and clamp turn vertically upon the rod I, and the front end of the beam A turns horizontally between the rear end of the clamp, thus giving to each beam H a universal movement.

Serial No. 303,885. (No model.)

In order to move all four of the cultivators together as if one, there is rigidly secured to each cultivator a socket N, and upon this socket is mounted the forked turning casting 0, between which the ends of thcconnectingrods are fastened. The four cultivators are divided into two pairs, and each pair is connected together by an arched connectingrod P, and then the two pairs of cultivators are connected together by the bent rod Q. All of the rods are perforated at their ends so as to adjust the distance between the cultivators, and through each casting is made a perforation, so that a lockingpin can be passed through and thus connect the rods together, so as to hold the cultivators always the same distance apart. As the castings O freely turn upon their sockets N and O, and as the rods P Q are jointed together, it will readily be seen that every cultivator has a free vertical play of its own. The rods P are arched, so as to pass over the corn or other growing plants, as each pair of cultivators is to work upon opposite sides of a row. Each of the outer cultivators being provided with a handle R, which projects inwardly, and all four of the cultivators being connected together by the bars P Q, a person walking behind can cultivate two rows of corn at the same time, thus effecting a great saving in time and expense. Ordinarily, to cultivate two rows of corn, two cultivators, four horses, and two drivers are required,while by the construction here shown this work can be done with three horses, one driver, and one machine.

Having thus described my invention, I claim The combination of the cultivator H, with the sockets N secured thereto, the castings placed upon the sockets, and the connectingrods P Q, for connecting the cultivators together, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
